Adele really goes all out when she's having fun, last week she absolutely nailed Halloween with an incredible The Mask costume, and now she's the latest star to join the #MannequinChallenge.

Sharing a clip on her social media pages, Adele went for a bar-inspired set up to Johnny Cash's Man in Black.

Surrounded by her pals and tour crew, Adele rocked a cowboy hat, while they stood still in a saloon – with one pretending to throw a chair.

The #MannequinChallenge craze has been taking over this weekend, and clearly the Someone Like You star couldn't resist.

The new craze requires participants to adopt a variety of 'action' poses, and then stand perfectly still while someone with a camera walks around filming the strange scenes.

And the results are almost eerie, showing people high-fiving, fighting, and even just simply frozen while walking.

Many of the videos have been set to Rae Sremmurd's track Black Beatles.

Adele's video comes after she beat One Direction to be crowned the richest British celebrity under 30, ending the boyband's three-year reign.

The All I Ask hitmaker is reported to have a more than doubled her estimated worth with £92 million, compared to the £38.1 million figure that saw her come in at fourth place on last year's Heat list of the 30 Richest British stars under 30.

The magazine's annual list has Harry Potter star Daniel Radcliffe in second place, with an estimated worth of £74 million. Singer Ed Sheeran is a new entry to the list in third place, with an estimated fortune of £45 million.

This is the sixth year the celebrity magazine has released the list, which is compiled by a number of industry experts. The panel looks at endorsement deals, television contracts, movie profits and record sales to determine the wealth of each celebrity.

Heat editor Suzy Cox said: "Adele has been unstoppable this year with her album release and stadium tour, so it comes as no shock that she has come out on top."

The full list of the 30 Richest Celebrities under 30 appears in this week's Heat, on sale from November 8th.
